Erik (Feb 01 2020 at 13:54):are you familiar with undo list/graph implementations? If so, you'll know what you need in your state atoms, so creating the mapping from db alterating internal commands is the next challenge, right?
Sean (Feb 03 2020 at 17:47):@scorp08 that depends on where a notion of undo should be supported. for example, is this a property of geometry (so if you send me geometry, if you allowed it, I could go back through the history and possibly undo changes, possibly even with a different application)? or is this a property of the application (so I can undo during my current editing session, possibly during future sessions with the same app)?
Sean (Feb 03 2020 at 17:50):traditional undo is of course typically limited to the current running application only (not a property of geometry), and for that, there's nearly limitless possibilities. one could simply look at the last command, and do the opposite
